Gorrilla Glass material

I'm modeling iPhone drop tests in ANSYS to look at the effects of various case geometries, however, I'm having a lot of trouble deciding on how I want to create the gorrilla glass material. Corning provides the Young's modulus, Poissons ratio, shear modulus, and density; thats about it. I don't believe this is enough to fully define the glass (I just want to see the principle stress effects, doesnt need to shatter necessarily). My question is: is there a material in the 18.1 ANSYS explicit dynamics materials library that is remotely similar? Float Glass is the only other glass I identified.

If you don't yet need to predict failure of the glass, then you have enough material properties to predict stress effects.

I recommend you try Transient Dynamics for simulating a drop test because I had good results and the solution times were reasonable.

I recently tried Explicit Dynamics and found that a simple problem ran for 33 hours on a mesh that was too coarse to be useful.

Ok thank you! I'll be sure to give transient dynamics a try

How can you study the creeping phenomena in transient dynamics?

Creep phenomena are on very long time scales. Fence14 is simulating drop tests, which means impact on a millisecond time scale.
